Exploration of the active site of β4GalT7 – Synthesis of substrates and inhibitors

Ytan av alla celler är dekorerad med kolhydrater som står för mycket av den information en cell överför till omgivande celler. Många av kolhydraterna tillhör en föreningsklass som kallas proteoglykaner som består av ett protein sammanbundet med en eller flera långa kolhydratkedjor. Dessa kolhydratkedjor kallas glykosaminoglykaner och är bundna till proteinet via kolhydraten xylos. Än så länge har β-1,4-Galactosyltransferase 7 (β4GalT7) is a key enzyme in the biosynthesis of proteoglycans (PGs) and glycosaminoglycan (GAG) chains, which are important macromolecules involved in many biological processes such as cell growth and cell signaling as well as in cancer pathobiology and viral and bacterial infections. Despite its pivotal role, much is still unknown regarding the specific structure of

Microstructure alterations in the hypothalamus in cranially radiated childhood leukaemia survivors but not in craniopharyngioma patients unaffected by hypothalamic damage

Objective: Metabolic complications are frequent in childhood leukaemia (ALL) survivors treated with cranial radiotherapy (CRT). These complications are potentially mediated by damage to the hypothalamus (HT), as childhood onset (CO) craniopharyngioma (CP) survivors without HT involvement are spared overt obesity. Diffusion tensor imaging (DTI) shows brain tissue microstructure alterations, by frac

Aggregates of Monotonic Step Response systems : a structural classification

Complex dynamical networks can often be analysed as the interconnection of subsystems, to simplify the model and better understand the global behaviour. Some biological networks can be analysed as aggregates of monotone subsystems. Yet, monotonicity is a strong requirement and relies on the knowledge of an explicit state model. Systems with a Monotonic Step Response (MSR), which include input-outp

A bounded complementary sensitivity function ensures topology-independent stability of homogeneous dynamical networks

This paper investigates the topology-independent stability of homogeneous dynamical networks, composed of interconnected equal systems. Precisely, dynamical systems with identical nominal transfer function F(s) are associated with the nodes of a directed graph whose arcs account for their dynamic interactions, described by a common nominal transfer function G(s). It is shown that topology-independ

Aggregates of Positive Impulse Response systems: a decomposition approach for complex networks

To simplify the analysis of complex dynamical networks, we have recently proposed an approach that decomposes the overall system into the sign-definite interconnection of subsystems with a Positive Impulse Response (PIR). PIR systems include and significantly generalise input-output monotone systems, and the PIR property (or equivalently, for linear systems, the Monotonic Step Response property) c

Incidence, characteristics, and outcome of solitary plasmacytoma and plasma cell leukemia. Population-based data from the Swedish Myeloma Register

Solitary plasmacytoma (SP) and plasma cell leukemia (PCL) are uncommon (3-6%) types of plasma cell disease. The risk of progression to symptomatic multiple myeloma (MM) is probably important for the outcome of SP. PCL is rare and has a dismal outcome. In this study, we report on incidence and survival in PCL/SP, and progression to MM in SP, using the prospective observational Swedish Multiple Myel

Nonsteroidal anti-inflammatory drugs and the risk of anastomotic leakage after anterior resection for rectal cancer

Background: Nonsteroidal anti-inflammatory drugs (NSAIDs) have been widely used in colorectal surgery due to their opioid-sparing effect. However, several studies have indicated an increased risk of anastomotic leakage following NSAID treatment, although conflicting results exist. The primary goal of this study was to further examine whether postoperative NSAIDs are independently associated with a

Gonadotropin-releasing Hormone Agonists, Orchiectomy, and Risk of Cardiovascular Disease : Semi-ecologic, Nationwide, Population-based Study

Background: In observational studies, men with prostate cancer treated with gonadotropin-releasing hormone (GnRH) agonists had a higher risk of cardiovascular disease (CVD) compared to men who had undergone orchiectomy. However, selection bias may have influenced the difference in risk. Objective: To investigate the association of type of androgen deprivation therapy (ADT) with risk of CVD while m

Association of the oestrogen receptor beta with hormone status and prognosis in a cohort of female patients with colorectal cancer

Background The oestrogen receptor beta (ERβ) is the predominant oestrogen receptor in the normal colon mucosa and has been reported to exert anti-proliferative and pro-apoptotic effects. However, the role of ERβ in colorectal cancer (CRC) progression remains unclear. Aim To investigate the role of ERβ and its association with hormone status and lifestyle indicators in a female cohort of patients w

New Genes Causing Hereditary Parkinson’s Disease or Parkinsonism

Purpose of Review: This article reviews was to review genes where putative or confirmed pathogenic mutations causing Parkinson’s disease or Parkinsonism have been identified since 2012, and summarizes the clinical and pathological picture of the associated disease subtypes. Recent Findings: Newly reported genes for dominant Parkinson’s disease are DNAJC13, CHCHD2, and TMEM230. However, the evidenc

Neuroacanthocytosis - Clinical variability (a report on six cases)

Objective: To provide clinical clues to differential diagnosis in patients with chorea and other movement disorders with blood acanthocytes. Background: Neuroacanthocytosis (NA) is an umbrella term for neurological conditions associated with acanthocytosis. Core NA syndromes, with basal ganglia involvement and in which acanthocytosis is a frequent finding, include autosomal recessive choreaacantho

Geografisk tillgänglighet för cykling i städer - Underlag för modellutveckling

Stads- och trafikplanering är komplext och som konstaterades inledningsvis i denna rapport har cyklingen generellt sett minskat i Sverige och svenska städer trots målsättningar och ambitioner om motsatsen. En möjlig orsak till detta är att det dels är svårt att skapa sig en samlad överblick över vilka faktorer som påverkar valet att cykla, dels är svårt att skapa sig en samlad överblick över hur d

Administrative Reforms and Decentralization : India and Indonesia

The paper compares the broad outlines of decentralization taking place in India, dating from the last decade of the past century, with that of Indonesia in the first decades of the present one. It focuses on the generally acknowledged least successful of reforms, namely that of public administration. Public administration tends to reflect the respective country’s prevailing norms. The paper opens
